1. For better grip, flip the bobby pin over so that the wavy side is against your head.

If you have a hard time keeping your bobby pins in place, try flipping the pin over. The straight side is slicker and won't grip as well as the wavy, more textured side.

2. Spray dry shampoo or texture spray on the bobby pin before insertion to prevent slippage.

Spritz a spray like Oribe Dry Texture Spray on the inside of the bobby pin to give it a little more grip. For the above look (tutorial here), tease the ends of the hair with a rattail comb before slipping the pins in for added hold. (Tip via stylist Dominick Pucciarello from Mizu Salon in NYC.)

3. Use the "locking" technique to ensure your pin stays in place all day.

Using a larger bobby pin or hairpin like Nishida Hair Pins, aim the open end of the pin against the direction that your hair is pulled. Next, rotate the pin so the open end is facing the same direction as the hair, and push the pin in toward your head to secure it. If inserted correctly, the pins will pull your hair tighter and be unnoticeable. Repeat these steps until your style is completely secure. (Tip via Matrix artistic director Ammon Carver.)

4. Secure the end of a braid with a hidden bobby pin to make your style look more chic.

For a sexy, blown-back look like Chrissy Teigen's, you'll want to discreetly pull your hair back with pins. "For the Academy Awards, I put a bobby pin on both sides of Chrissy's head right behind her ears so no one could see them," stylist Pucciarello told Cosmopolitan.com. "That way, she wouldn't have to keep running her hands through her hair, and it wouldn't fall forward or off to the sides."

Braid a section of your hair (about the width of your pinky), and pull it back. With the open end toward your face, place one foot of the bobby pin against your head and below the braid, and the other side against your head above the braid, and slide the pin forward into place.

If you're looking for a way to pull back the sides of your hair but don't want the pins to show, try this simple technique: Insert a bobby pin with the open end pointing toward your face and in the opposite direction of the section you're pinning back. If one bobby pin isn't strong enough, try using a larger one or reinforce it with a second pin right below.

Pull small sections of hair from each side of your head and cross them in the back. While holding your hair in place, take a bobby pin and slide it in horizontally over the crossed section. Then take another bobby pin and slide it upward at a diagonal angle to set the right side. Repeat this on the left to complete the triangle.

Start by pinning your bangs with one bobby pin with the open end toward the ceiling. Complete the "V" shape by sliding one leg of another bobby pin at a downward angle inside the looped end of the first pin. Repeat as many times as you'd like to get the look you want.

12. Cross pins on top of each other for reinforcement and a cool look.

To make sure the first pin stays closed, pin another one over it in an "X" shape to help keep it shut.

Once you've put your hair in a ponytail, insert two or three bobby pins halfway inside the elastic and facing downward toward the crown of your head. Then, fluff your ponytail and flip it over for a fuller look that won't sag or droop.

15. Make your curls last longer by pinning the sections after curling them until they've cooled.

After you've released a section of hair from your curling iron, immediately roll the strand back up and pin it against your head. Once you've pinned all the sections up, wait for them to cool to room temperature and then take out the pins. This technique will help your curls from falling flat right after you've curled them.

16. Give your side pony more volume by teasing and pinning the hair at your crown first.

To make your side ponytail look more voluminous, backcomb small sections of hair at the crown of your head and then smooth them over and pin them back. Gather all of your hair into a ponytail for the finished look.
